I have a 2001 Chrysler Concord that has been draining the battery. Took it to get checked out and no one has been able to find any short or problems with the alternator or electrical.

About a month ago we noticed the interior lights blinking on and off and we figured that was the problem. It doesnt do that anymore.

Put a battery in last Wednesday and it was dead on Saturday. Only lasted 3 days. The shop where took it said it wouldnt hold a charge. I have a feeling its not just a bad battery.

Anyone had similar problems with their Concord?

Can't help with the battery but with blinking lights try working the switch to clean the contacts. Chrysler reads resistance to multiplex some of the simple stuff and a dirty switch will throw things off.

While some things like cruise control switches are resistance multiplexed on a single wire, the interior light dimming is not. It is a simple variable resistor wiper whose output goes to the BCM for direct reading on a dedicated wire. But you're right that that switch is the problem - putting it into a different position or doing as you suggested can help.
